Abstract
A safety razor has a handle (1) and a head structure (5) mounted for pivotable movement relative to the handle during shaving. The head structure (5) includes a motor (18) housed in a sealed chamber (9) for driving a device in use of the razor, such as to reciprocate a guard component or a blade, to vibrate the head structure, to actuate a dispensing device for delivering a shaving enhancement fluid, or to oscillate a support platform (101) on which a blade unit (110) is mounted. The shaving cartridge can include a guard component (38) with projections (39) which are moved towards and away from the skin being shaved when the guard component is reciprocated by the motor (18).
Claims29
A safety razor comprising
- a handle (1);
- a head structure (5) pivotally connected to the handle, the head structure being pivotable relative to the handle in use of the razor;
- a motor-driven device;
- and
- a motor (18) for actuating the motor driven device,
- characterised in that the motor (18) is located within the head structure (5).
A safety razor according to any one of the preceding claims, wherein the head structure (5) includes a mounting structure (36) for detachably mounting a shaving cartridge (30) thereon.
A safety razor according to any one of the preceding claims, wherein the motor (18) has a rotary output member (20) coupled to a mechanism to convert rotary motion of the output member into a reciprocal motion.
A safety razor according to any one of the preceding claims, wherein the motor driven device operates a movable skin contacting component (32;
- 38).
A safety razor according to any one of the preceding claims, including a dispensing device to deliver a shaving enhancement fluid at the head structure, the dispensing device being operable by the motor.
A safety razor according to any one of the preceding claims, including a hair trimmer capable of being driven by the motor.
A safety razor cartridge comprising a frame (31) carrying at least one blade (32) having a sharp cutting edge, and a guard component (38) for contact with the skin in front of the at least one blade during shaving, the guard component having elements (39) for engagement with the skin at discrete locations, characterised in that the guard component (38) is guided in the frame (31) for reciprocation by a drive mechanism in a direction for movement of the elements towards and away from the skin.
